I'm not sure if it's excessive or just remarkably thorough,* but Baseball Tonight is currently in the middle of a project to rank baseball's top 500 players for the 2013 season. I'll let ESPN explain how they made the list:
34 ESPN experts, who were polled in the final two weeks of February, started with a list of more than 600 players. Using a 0-to-100 scale, they evaluated the players based only on how well they will perform in 2013.
Jean Segura, #410. Segura's age 23 season and likely first full year in the majors coincides with his first year on this list. Being ranked at this spot puts him ahead of new A's shortstop Hiroyuki Nakajima (#414), Diamondbacks shortstop Cliff Pennington (#415) and Mariners shortstop Brendan Ryan (#431).
Wily Peralta, #450. Like Segura, this is Peralta's first real opportunity to make this list. By putting him at 450 ESPN rated him just behind Cardinals starter Joe Kelly (#448) and White Sox reliever Matt Lindstrom (#449) but ahead of Marlins pitcher Jacob Turner (#451) and Mariners righty Erasmo Ramirez (#454).
Chris Narveson, #465. Narveson was #362 on this list a year ago, so his lost season and question marks about his surgically-repaired shoulder cost him pretty significantly here. He ranks one spot behind former Brewer and human walk machine Jose Veras (#464).
Tom Gorzelanny, #498. One of the last Brewers on the list was nearly the last player on the list, as the Brewers' biggest offseason acquisition checks in at #498. Gorzelanny was #480 a year ago, so not much has changed.
Players ranked #301-400 will be unveiled tomorrow.
